    Undergrad Solve 3^(2x) - 2*3^(x+5) + 3^10 = 0 - Brain Boosting Hint

    Sheesh! I had tried this by letting u = 3^x but made an error and gave up when it didn't work out. Thanks. I feel better now.

    Undergrad Solve 3^(2x) - 2*3^(x+5) + 3^10 = 0 - Brain Boosting Hint

    Looking to solve for x. It is a homework problem... one that I assigned. I teach this for a living and although I'm sure there's something relatively simple that I'm missing, for the life of me I don't see it now. This is a review problem in precalculus so it doesn't involve calculus to...

    Undergrad Solve 3^(2x) - 2*3^(x+5) + 3^10 = 0 - Brain Boosting Hint

    Can someone give me a starter hint for this problem? Brain's not working at full speed... 3^(2x) - 2*3^(x+5) + 3^10 = 0 Thanks
